Title: Production of polyester film
Inventor: TSUNASHIMA KENJI
IPC: C08J5/18
Filed: 1987-02-13
Abstract: PURPOSE:To obtain a high strength film having no surface flaw without using a rubber roll, by melting a polyester pellet in gas containing at least 1 vol.% of carbon dioxide to form the same into a film by extrusion molding and stretching the film 4.5 times or more in the longitudinal direction thereof followed by applying stretching and heat treatment thereto in the lateral direction. CONSTITUTION:A polyester pellet is supplied to an extruder under an atmosphere containing at least 1 vol.% of CO2 and melted. The molten polyester sent out from the extruder passes through a filter and is quantitatively supplied by a gear pump to be guided to a molding die and emitted from a die slit to form a molten sheet which is, in turn, brought into close contact with a casting drum for cooling and solidifying the molten sheet to obtain a molded sheet. The molded sheet is stretched in the longitudinal direction by a metal roll which has a surface coated with metal material by chromium plating and increased in surface hardness, abrasion resistance and scratch resistance. The stretching system in the longitudinal direction is pref. a no-nip system. Stretching magnification is set to 4.5 times or more and stretching temp. is set to the glass transistion temp. of the polyester pellet or more. Next, the stretching in the lateral direction and heat treatment are performed.

Title: Manufacture of semiconductor device
Inventor: SERIKAWA TADASHI
IPC: H01L21/3065
Filed: 1981-03-04
Abstract: PURPOSE:To allow the high yield manufacture of high reliability semiconductor device with high withstand voltage, by flattening the surface of semiconductor element. CONSTITUTION:A conductive layer 12 is formed on a semiconductor substrate 11. Next a resist 13 treated with patterning is formed on this layer 12, and then etching is done with the resist 13 as a mask to form a conductive layer 12a with bevel trail. Subsequently an insulative layer 14 is formed on the whole sunface by sputtering. In this case, the insulative layer 14a formed at the bevel trail has minute density by the same degree as the insulative layer 14b and 14c formed on a flat surface. On the contrary, the insulative layer 14d formed on the side of the resist 13 has less density. Consequently, when the substrate 11 is etched, only the layer 14d is selectively removed. Next the layer 14c on the upper surface is lifted off with the resist 13. As the result, the structure having a flat element surface is obtained. Thus, a flat conductive layer 16 is formed on the substrate via the insulating layer 15.
